Typesets by IMSLP contributor found elsewhere

This is about count van Wassenaer's six Concerti Armonici [1]. I've found very good editions of most of them on archive.org (example [2]), by one Thomas A. Schneider, who I'm strongly betting is IMSLP user "Theatersokrates" [3], with a composer page [4] referencing 21 editions by him, all under CC BY-NC. I'd love to get the Concerti Armonici on IMSLP and would love to assume the same license is intended for these editions, but there is no mention of terms in the copyright notice itself. I emailed him about this a week ago using the address found here [5], and written a post on his talk page before that [6], with no response. What should I do now? It's tantalizing that this happens to be a prolific IMSLP contributor!

This is a bit of an odd case. Schneider's edition on archive.org originated from IMSLP. If you click the "show more" button it will show you the source and the url given leads you to this deleted page on IMSLP. Back in 2012 a large chunk of IMSLP scores were backed up to archive.org and this one was among those. In May, 2013 the file for Concerto armonico No.1 on IMSLP (and the now-empty work page) was deleted at the editor's request. I cannot find in either the page's history or the contributor's talk page the reason for doing this. Back then there was an unwritten understanding that allowed contributors (mostly composers) posting scores under a CC license to request their removal which was then usually fulfilled. Thankfully we now abide by the CC license and so no CC-licensed scores will be removed from the site. In this case I'd suggest that unless you receive a reply from Schneider granting you permission to post it to IMSLP that the score from archive.org should not be re-uploaded to IMSLP as that score has no CC license imprinted on any of the pages but it does clearly have a copyright notice by Mr. Schneider.

Thank you for the reply. Very strange indeed.
